Novak Djokovic gave Serbia more to celebrate at the French Open when he outplayed Russia's [Images] Igor Andreev 6-3, 6-3, 6-3 on Wednesday to reach the semi-finals of a Grand Slam tournament for the first time.

The youngest player left in the draw at 20, Djokovic taught Andreev a tennis lesson to join women compatriots Jelena Jankovic and Ana Ivanovic in the last four of the showcase claycourt event.

Djokovic, seeded sixth, will meet a Spaniard, either defending champion Rafael Nadal [Images] or Carlos Moya [Images], for a place in Sunday's final.

Andreev, who has dropped to world number 125 after being sidelined for six months last year following knee surgery, was never in contention.
